Ciamillo rear brake servicing - removing excess play
Posted: Sat Dec 17, 2016 6:17 pm
Hello
I have now managed to install my Ciamillo Negative Gravity SL brakes. Actually proved less of a hassle than I expected and the action of the brakes and their resilience looks good.
The set I have installed were bough secondhand and while the front one is perfect I have noticed something odd about the rear - when the brake pads are gripping the rim and I then rock the bike forward and back, there is quiet a lot of movement in the brake arms, probably 5-7mm.
This clearly isn't ideal. Aside from this issue the brake is in very good condition with no damage, corrosion, or other signs of mechanical wear/bends/etc.
On further investigation it looks like the elements of the brake need to be tightened together (I can get it centred in the frame no problem, what I am referring to here is reducing the distance between the two brake arms at the point where they pivot around the central bolt).
I have tried to undo the brake by putting a 13mm spanner onto the main nut and an allen key into the outer end of the brake bolt but even with reasonable force it won't budge.
Does anyone have experience of this issue and how to fix the excessive play?
